Physical limits and information bounds of micro control. II. Quantum soft computing and quantum searching algorithms

S.V. Ulyanoy, Giovanni Degli Antoni, K. Yamafuji +3 more

Principles of quantum soft computing, models of fast quantum searching algorithms and the possibility of its applications for intelligent control of micro-systems are introduced. The description problem of searching and decision-making support processes from more fundamental mutual positions of the new information technologies and a modern physics, information physics, are discussed: (1) in the quantum information theory-the information complexity theory of random symbolic sequences, computation complexity, quantum searching algorithms; and (2) in the modern physics-nonequilibrium thermodynamics and quantum mechanics.

The complexity of a quantum system and the accuracy of its description

Yuri Ozhigov

The complexity of the quantum state of a multiparticle system and the maximum possible accuracy of its quantum description are connected by a relation similar to the coordinate-momentum uncertainty relation. The coefficient in this relation is equal to the maximum number of qubits whose dynamics can be adequately described by quantum theory, and therefore it can be determined experimentally through Grover search algorithm. Such a restriction of the Copenhagen formalism is relevant for complex systems; it gives a natural description of unitary dynamics together with decoherence and measurement, but also implies the existence of a minimum non-zero amplitude size, as well as a restriction on the equality of bases in the state space. The quantization of the amplitude allows us to formally introduce a certain kind of determinism into quantum evolution, which is important for complex systems.
